Well, I haven't been here for 3 years, but the best restaurants for me are the Plaza Cafe and Maria's New Mexican Kitchen (that's New Mexican, not a new Mexico-style) kitchen.

I bought Maria's Mexican cooking book and have used it for 15 years or so--with positive results every time.

Besides the obvious tour of the Governor's Mansion downtown, the oldest church in America is also downtown--and my wife and I always go shopping not only for jewelry downtown, but also for pottery and sculptures and other New Mexican designed stuff at Jackalope out on Cerrillos Road just a short ways south of downtown. Besides Santa Fe, there are also interesting inner city areas near Albuquerque and in Taos--both places about 1-2 hours away. There is also a tram you can take to the top of Sandia Mountain south of town. Enjoy.
